Description

Technical Field

[0001] The utility model relates to a tractor, in particular to a tractor with a plow replacement function. Background Art

[0002] Tractors are important agricultural machinery. Early tractors were based on steam or internal combustion engine technology, using a power unit to drive wheels, enabling mechanization of various operations such as tillage, sowing, and harvesting. With technological advancements, modern tractors have integrated advanced technologies such as electronics and intelligent control, improving operational precision and efficiency while reducing labor costs. They have become an indispensable tool for modern agriculture and have significantly promoted agricultural modernization. The plow, a key agricultural implement supporting the tractor and used for tilling and breaking up the soil, is a key tool for increasing crop yields and incomes.

[0003] Traditional plow replacement operations have long relied on manual disassembly and installation. This process is not only extremely labor-intensive and physically demanding for the operator, but also usually requires the collaboration of multiple people to complete. In addition, the entire replacement process is time-consuming and inefficient. Operators need to spend a lot of time and energy on tedious bolt removal, reinstallation, and calibration adjustments. This undoubtedly seriously hinders the rapid advancement of agricultural production processes and slows down the overall operation pace. Utility Model Content

[0004] In order to overcome the disadvantage that it is inconvenient to replace the plow of a tractor, the technical problem of the utility model is to provide a tractor with a plow replacement function.

[0005] The technical implementation scheme of the utility model is: a tractor with a plow replacement function, including a tractor, a plow, a support plate, a positioning rod, a connecting frame, a lifting device, a first hydraulic cylinder, a connecting rod, a positioning block and a second hydraulic cylinder. A lifting device is provided at the rear of the tractor, and the lifting device is provided with a first hydraulic cylinder, the output shaft of the first hydraulic cylinder is connected to the connecting rod, a slide groove is provided on the positioning block, the connecting rod is slidably connected to the slide groove of the positioning block, two second hydraulic cylinders are installed at the lower end of the positioning block, a support plate is provided on the upper part of the plow, a positioning rod is provided on one side of the upper end of the support plate, and two connecting frames are provided on the other side of the upper end of the support plate.

[0006] More preferably, the lifting device includes an electric slide rail and a sliding plate, the electric slide rail is installed at the rear of the tractor, the slider of the electric slide rail is connected to the sliding plate, and the first hydraulic cylinder is installed on the sliding plate.

[0007] More preferably, an elastic member is further included. The connecting rod is provided with the elastic member, and the elastic member is connected to the positioning block.

[0008] More preferably, the positioning block is provided with a slot matching the positioning rod.

[0009] More preferably, a support frame is further included, and the support frame is provided at the rear of the tractor.

[0010] More preferably, a limit plate is further included. A limit plate is provided between the two connecting frames on the upper side of the support plate. The shape of the upper side of the limit plate matches the output shaft of the second hydraulic cylinder. The middle part of the upper side of the limit plate is a soft layer structure.

[0011] Compared with the prior art, the utility model has the following advantages: 1. The utility model can easily realize the installation and disassembly of the plow through the positioning function of the first hydraulic cylinder, the positioning rod and the positioning block, thereby improving the working efficiency and flexibility. By setting the lifting device, the height of the positioning block can be conveniently adjusted to adapt to different working environments and needs. The setting of the elastic part can compensate for the positioning error caused by component tolerance, wear or deformation to a certain extent, and assist in achieving more precise positioning through slight deformation. The card groove on the positioning block that matches the positioning rod further reduces the positioning error.

[0012] 2. Through the design of the support frame, the utility model can support the positioning block when the plow is disassembled and no longer in use, thereby reducing the pressure on the first hydraulic cylinder and helping to extend the service life of the first hydraulic cylinder. The limit plate can provide buffering and shock absorption effects when the output shaft of the second hydraulic cylinder contacts the limit plate, reducing wear and damage to the output shaft of the second hydraulic cylinder caused by direct collision.

DETAILED DESCRIPTION

[0020] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] A tractor with a plow replacement function, such as Figures 1 to 6 As shown, it includes a tractor 1, a plow 2, a support plate 3, a positioning rod 4, a connecting frame 5, a lifting device 6, a first hydraulic cylinder 7, a connecting rod 8, a positioning block 10 and a second hydraulic cylinder 11. A lifting device 6 is provided at the rear of the tractor 1, and a first hydraulic cylinder 7 is provided on the lifting device 6. The output shaft of the first hydraulic cylinder 7 is connected to the connecting rod 8. Slide grooves are provided on the front and rear sides of the positioning block 10. The connecting rod 8 is slidably connected to the slide groove of the positioning block 10. Two second hydraulic cylinders 11 are symmetrically installed at the lower end of the positioning block 10. A support plate 3 is provided on the upper right side of the plow 2, a positioning rod 4 is provided on the left side of the upper end of the support plate 3, and a slot matching the positioning rod 4 is provided on the left end of the positioning block 10. Two connecting frames 5 are provided on the right side of the upper end of the support plate 3. The upper ends of the two connecting frames 5 are provided with through holes for the output shaft of the second hydraulic cylinder 11 to extend into.

[0022] When installing the plow 2, the lifting device 6 moves the first hydraulic cylinder 7 and the components connected to it to a suitable height, and then the output shaft of the first hydraulic cylinder 7 extends, driving the connecting rod 8, the positioning block 10 and the second hydraulic cylinder 11 and other components to move to the left. When the positioning rod 4 is embedded in the groove on the left side of the positioning block 10, the first hydraulic cylinder 7 stops, and the output shaft of the second hydraulic cylinder 11 extends into the slot of the connecting frame 5, completing the installation of the plow 2. When the plow 2 needs to be disassembled, the output shaft of the second hydraulic cylinder 11 retracts away from the connecting frame 5, and then the output shaft of the first hydraulic cylinder 7 retracts to drive the positioning block 10 away from the positioning rod 4, completing the disassembly of the plow 2.

[0023] like Figure 5As shown, the lifting device 6 includes an electric slide rail 61 and a sliding plate 62. Two electric slide rails 61 are installed at the rear of the tractor 1. The sliders of the two electric slide rails 61 are connected to the sliding plate 62. The first hydraulic cylinder 7 is installed in the middle of the sliding plate 62. When the height of the positioning block 10 needs to be adjusted, the electric slide rail 61 is started, and the slider of the electric slide rail 61 drives the sliding plate 62 to move. The sliding plate 62 will drive the first hydraulic cylinder 7, the connecting rod 8 and the positioning block 10 and other components to move. When the left slot of the positioning block 10 is aligned with the positioning rod 4, the electric slide rail 61 stops.

[0024] like Figure 6 As shown, an elastic member 9 is also included. Elastic members 9 are provided at both ends of the front and rear ends of the connecting rod 8, and the four elastic members 9 are all connected to the positioning block 10. The elastic member 9 is located in the slide groove of the positioning block 10. Since the elastic member 9 has a certain elasticity and restoring force, it can compensate for the positioning error caused by component tolerance, wear or deformation to a certain extent. When the positioning block 10 is docked with the positioning rod 4, the slight deformation of the elastic member 9 is used to assist in achieving more precise positioning, ensuring that the positioning block 10 can be accurately embedded in the card slot of the positioning rod 4.

[0025] like Figure 3 As shown, a support frame 12 is also included. The support frame 12 is provided at the rear of the tractor 1. The shape of the left end of the support frame 12 matches the second hydraulic cylinder 11. When the plow 2 is disassembled and no longer needed, the positioning block 10 can be lowered by the electric slide rail 61. The support frame 12 will contact the second hydraulic cylinder 11 and support the positioning block 10, thereby reducing the pressure on the first hydraulic cylinder 7 and extending its service life.

[0026] like Figure 2 、 Figure 4 and Figure 6 As shown, a limiting plate 51 is also included. A limiting plate 51 is provided between the two connecting frames 5 on the upper side of the support plate 3. The shape of the upper side of the limiting plate 51 matches the output shaft of the second hydraulic cylinder 11. The middle part of the upper side of the limiting plate 51 is a soft layer structure. When the plow 2 is installed, the output shaft of the second hydraulic cylinder 11 will contact the middle part of the upper side of the limiting plate 51. The limiting plate 51 can provide buffering and shock absorption effects when the output shaft of the second hydraulic cylinder 11 contacts the limiting plate 51, thereby reducing wear and damage to the output shaft of the second hydraulic cylinder 11 due to direct collision.

[0027] The technical principles of the embodiments of the present invention have been described above in conjunction with specific embodiments. These descriptions are intended solely to explain the principles of the embodiments of the present invention and should not be construed in any way as limiting the scope of protection of the embodiments of the present invention. Based on the explanations herein, those skilled in the art will be able to conceive of other specific implementations of the embodiments of the present invention without inventive effort, and these implementations will fall within the scope of protection of the embodiments of the present invention.
